Abstract

The purpose of this study was to investigate mix the effect of different levels of dietary biotronic organic supplement with and without silymarin nanocrystal on growth performance, carcass characteristics and meat quality of broiler chicks. This experiment was conducted in a 2×4 factorial arrangement with completely randomized design using 384 day-old broiler chicks in 8 treatments, 4 replications and 12 chicks per each replicate. The factors of interest included two levels of silymarin nanocrystal (with silymarin nanocrystal and without Silymarin nanocrystal) and four levels of biotronic supplement (0, 50, 100 and 150 mg/kg). The results showed that the utilization of biotronic organic supplement caused a decrease in feed intake and improvement of body weight gain and feed conversion ratio in all production periods (P<0.05). The utilization of silymarin nanocrystal had a significant effect on feed conversion ratio only in finisher period in comparison initial peiod and growth. Also, the use of silymarin nanocrystal caused significant increase in carcass charectristics in comparison treatmentsilymarin nanocrystal (P<0.05) while biotronic organic supplement significantly reduced liver and abdominal fat weights (P<0.05). biotronic organic supplement caused increase in thigh moisture percentage and decrease in post-slaughter malondialdehyde concentration in comparison without nanocrystalsilymarin and bioteronic supplement.Also, the utilization of biotronic organic supplement could decrease malondialdehyde content at 30 days post-slaughter. Generally in comparison control treatment.the interaction was not significant in any parameter, the use of biotronic organic supplement of the diet improved performance, carcass characteristics and meat quality.
